I am working on a BlackBerry application and I need a way to find out the millis value of tomorrow morning at 1am. On Android, this would a job for Calendar.add(), or Calendar.roll(). But the Calendar class in BlackBerry doesn't seem to have either of these methods. Is my only option to do the arithmetic on millis values?
Take a look at DateTimeUtilities, specifically getNextDate(). I think that you can probably get it to do what you need with that.

I have a personal expenses app in which I have a Week model which holds user expanses over week and at the end of the week uploads it in cloud. My problem is that how can I implement a situation in which Week model is created at first day of week(eg.saturday) periodically even if the app is not running??? Is that even possible??
I searched a little and saw
timer.periodic(duration,callback);
but I don't think that would work in background
Maybe this will help you:
Firstly
You have to use Timer from dart:async to run periodically method, and put the duration for 7 days.
Timer.periodic(
Duration(days: 7),
(timer){
// Create new week model in database.
}
);
Secondly
Use workmanager to run the previous code in the background, it will executed weekly.
You can use background_fetch plugin. But this plugin's lack of it is that works stable on just Android. You need to read the official document.
I am currently developing an application with Flutter where I use the Google Maps API but I am having a problem with the display of data.
Indeed in my application it displays the arrival time (arrival_time) like this: 7:19pm.
But I would like it to display in this form: 19:19
Same for the travel time (duration) it displays 1hour24mins but I would like it to display 1h24.
How do I deal with these problems?
Thanks a lot for your help

Here is a screenshot:
If you can transform this dates to DateTime, then you could use intl package to transform the time.
For instance:
DateTime t = DateTime.now();
print(DateFormat.Hm().format(t));
This prints the time in 24 hours format.
You would also probably be able to also transform it to XhYm too.
Thanks a lot for your help.
So there you have it, I tried your solutions but it doesn't work.
What is strange is that when I call the API with a browser (Chrome) it displays the correct time (16:48).
But when I try in the app it returns 4:48 pm.
And suddenly I don't know how to solve this problem.
So if there are any additional parameters to pass, I would like to have them.
Thank you for your time

I have an electron application, and a requirement is to call the mac's api to add related schedules, as shown in the figure:
I want to use swift for development, and then package it into a node addon for electron to call, but I am not very familiar with swift and mac api.
I don't know how to write related swift code and which api to call to complete the function of the above picture.
I tried AppleScript, but it seems that I can't choose calendar contains freely.
Here is the applescript code to try(unable to meet demand):
set theStartDate to (current date) + (1 * days)
set hours of theStartDate to 15
set minutes of theStartDate to 0
set seconds of theStartDate to 0
set theEndDate to theStartDate + (1 * hours)
tell application "Calendar"
tell calendar "Calendar Project"
make new event with properties {summary:"Important Meeting!", start date:theStartDate, end date:theEndDate}
end tell
end tell
Of course, if Objective-C and AppleScript can also do it, it is also possible.
Any hints would be helpful. Thanks!
If the above description does not describe the problem well, then I will ask in another way:
What API of macOS should be called in swift to pop up a Adding a new event window
The dialog in question is part of Calendar.app and AppleScript is the only way to invoke it, but this is clunky. The best way is to create your own UI and use EventKit to add the event based on the selections in the UI.
At first i tried this with the Calender-Class but then i read, that it is not supported by GWT. Do you have suggestions? Thank you in advance.
Since GWT 2.7 you can use JsDate.
Yes, you should use the deprecated Date API. You should probably create a utility class for such date manipulation, something like CalendarUtil, but for hours/minutes. If Calendar (or any alternative) is every ported to GWT (or a date time library surfaces that is actually maintained), you can change the implementation in your utility class and the rest of your application will remain the same.
